how to install hard drive into mac pro

http://manuals.info.apple.com/en_US/mac_pro_mid2010_ug.pdf

I recently bought a new 2TB internal sata drive for my Macpro.

The installation was easy, but I'm not sure what to do next.

For one, should I partition the drive?

My purpose for buying the drive was to use it as my go to drive for Parallels. I used to run my music studio on Windows based machines, and my older project files require a windows OS to recover. I installed Parallels so I can have my studio running Mac and Windows programs which will enable me to access my old project files and take them into my newer Protools system.

So now, I've installed my new hard drive, but I'm not sure if I should partition it....And!? I'm not sure how to designate that drive for my virtual pc on Parallels. I was able to allocate enough disk space to parallels in order to load my music software, but at this point, I'm not sure if I've just promised it disk space from my original partitioned drive (which only has about 350 GB left on it).

I would love to be able to make one internal drive available for Parallels, and the other available for the rest of my OSX. When I use Parallels, I still would like to save some extra information on the 2TB drive as well from my dekstop running OSX.

I hope this makes sense! Your help is much appreciated!

this is the first thing I saw after installing my new drive...and this:
